Status: AnalyzedCritical (9.1)—

An issue was discovered in Samsung Mobile Processor Exynos 1480 and 2400. The lack of a length check leads to out-of-bounds writes.

CVSS

Version: 3.1
Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H
Base score: 9.1

Exploitation probability (EPSS)

Probability of exploitation in the next 30 days: 0.43%
Percentile among all scored CVEs: 35
Score date: 10/6/2026

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
